Dead Eco 105
Bought a Gen1 105ah 48v Eco-Battery
Worked great for 800miles (in four months) Climbing a steep hill, it just "popped" and shut down. Dealer sent it back and a few weeks later they sent me the new version. The one with an on/off button. I hope this one is reliable. 03 DS 600amp Navitas D&D high speed |

Re: Dead Eco 105
The pop was probably the BMS. Possibly they did not have one that could handle the amp draw you were asking with your high speed motor and the 600a Navitas.
Most times the BMS would just shut down but obviously was not the case here. |

Re: Dead Eco 105
It was the BMS as per the guys at Eco
They are very good on customer service btw I had 38% charge and 52ish volts at the time I don't have the torque dialed very high, when I do it's insane I would like to use this cart in the Blue Ridge mountains but now I'm worried about overload from those hills. |

Re: Dead Eco 105
The Data Sheet says...
Max discharge for 3seconds is 600amps Max for 30sec is 300amps sounds like a lot to me I assume there's no way I could pull that ?? |

Talk with Eco and your controller manufacturer to dial in the correct settings for both, and you won't believe the performance around the Blue Ridge. |

My motor is DC. Don't know if that makes much difference. One comforting thing is..The placard on top of this Gen2 battery says 300amps max for 30second where the Gen1 battery said 200. That could be the threshold I was reaching?? My sisters live in Ellijay GA on a logging road at 2k elevation. Probably not as high as you but the road has some steep climbs here and there. I like the Regen on the Navitas as it would help with braking coming down inclines. The OEM brakes worry me at 25+ downhill. |

Re: Dead Eco 105
You need to limit your Navitas max amps to 300a maybe 250. No way that battery is going to put out 600 amps w/o triggering a low voltage fault. And it will only get worse as the weather gets colder.
